Abstract: The main principle of this project is to protect the buildings by constructing them as earthquake-resistant structures. Base Isolation is a flexible layer between the substructure and superstructure, uncoupling the structure from the damaging effects of ground motion to resist vibrations within the structure. It is essential to utilise high technology, such as base Isolation, which protects the structure against extreme earthquakes without compromising its performance. A comparative study is conducted on a G+15 story building with and without a Lead Rubber bearing, using IS 875:2015 and IS 1893:2016, with the response spectrum method. Considering the maximum vertical reaction obtained from the fixed base is used to design base isolators, the obtained stiffness is used in modelling by replacing the fixed base joints with base isolators in the buildings. Story displacement, Story drift, story, and Overturning moment shear are compared for both cases. In this case, we are using rubber base isolators for analyzing the structure using ETABS Software.
